D-Link F-series long-range PoE switches

D-Link has expanded its selection of long-range (250 m) Power over Ethernet (PoE) switches with the addition of a full gigabit range (DGS F-Series) to complement the existing 10/100 Mbps products (DES F-Series) on offer. Designed for surveillance systems integrators and companies who deploy camera and monitoring solutions.

Designed as part of D-Link’s entry-level unmanaged PoE switching solutions, the DGS F-Series sports Gigabit (1000 Mbps) on all ports, whereas the DES range comes with 100 Mbps per port, as well as Gigabit uplinks. All models have features including long-range PoE, VLAN, QoS and auto PoE reset functionality.

The 250 m PoE capability of the switches assists with deployments where a camera or a Wi-Fi access point needs to be installed at a distant location where the standard 100 m cable length is a limitation. When mixing video traffic with other traffic, users often want to apply priority to video streams to avoid video stutter and dropped frames. The switches offer a simple VLAN whereby users can easily isolate ports from each other, without the need for additional configuration, alongside automatic QoS to prioritise video and voice traffic.

The units include the ability to reset connected PoE devices using the automatic PoE reset function, or AI PoE. If a device, for whatever reason, stops responding, the switch automatically detects this and resets the electric current supplied to the device momentarily, causing the device to reboot itself.
